  • Patent number: 5516581
    Abstract: A removable adhesive tape comprising a highly extensible and substantially inelastic backing and a layer of pressure-sensitive adhesive. The backing has a high tensile strength, has a lengthwise elongation at break of at least about 150% with less than about 50% elastic recovery after stretching. The adhesive can be a normally tacky and pressure-sensitive adhesive and is coated on at least one surface of the film backing. The adhesive is preferably highly extensible, does not separate from the backing during stretching, and has higher cohesion than adhesion to any suitable substrate. After being applied to a substrate, the adhesive tape of the present invention becomes firmly bonded, but can be easily removed without damaging the substrate by simply stretching it in a direction substantially parallel, i.e., less than about 35.degree., to the surface of the substrate.

  • Patent number: 5198301
    Abstract: Films are provided made from ionomeric polymer resins with 2-40% by weight of a filler material, where the film has a thickness between 0.050 and 0.127 mm. These films are highly flexible and conformable. Adhesive composites comprising these films are also provided.

  • Patent number: 5196246
    Abstract: An improved wall decorating system is disclosed that utilizes a film comprising about 60-98% by weight ionomer resin that is a copolymer of ethylene and acrylic acid or methacrylic acid neutralized by a metal cation, the resin having a melt flow index greater than about 10 and about 2-40% by weight of a filler material, wherein the film has a thickness of between 0.050 and 0.127 mm. The wall decorating system also may include an improved adhesive comprising between about 60-100% by weight of hollow, polymeric, acrylate, inherently tacky, infusible, solvent-insoluble, solvent-dispersible, elastomeric pressure-sensitive adhesive microspheres having a diameter of at least 1 micrometer, and between about 0-40% by weight of a non-spherical polyacrylate adhesive.
